My mail server at office uses SMTP pot 25 and my ISP at home uses 587 for outbound mails. when i send any mails from home to my official mail-id it bounce back. i receive mails but sending mails is not happening.
Some one suggested to register my official (company) mail-id with Gmail and send mails to my office through gmail server. Is it possible to do so? if so how safe is it and whats is the procedure?
